SM-G781B CSC Change via SamKey - Samsung Galaxy S20 FE Questions & Answers

Hi!
I recently bought S20 FE 5G with snapdragon CPU (G781B). I need to change CSC from Polish Orange to XEO. I getting familiar with SamKey however I have incompatible firmware. As far I know there is no way to downgrade firmware because of bootloader compability.
Does anyone know if SamKey is still being developed or is it dead? Is there is any other method for changing CSC without voiding warranty? I have 3 phones in total to change CSC (mentioned G781B and two G991B).
BR,
Michael.

Did you use SamKey ?
Did it work?

Unlocking Samsung Note 9 N960U from USA in EU (SIM lock)

Hello everybody I have question about friends mobile. He bought it in USA from T-Mobile but now live in Europe. I think that there are 2 ways how to solve SIM lock right? First one: use some reliable but cheap service for unlocking by code. Second one: flash Android to global version? Can you tell me if it possible to flash N960U to some no SIM blocking Android? I flash some years ago some Samsung phones with ODIN, dont know if this can be used on phone sold in US.
I tried this https://forum.xda-developers.com/galaxy-note-9/how-to/n960u-tmb-stock-odin-files-firmware-t3833205 but it keep asks me for unlock network code
Thank you for any advices...

maybe try n960u1 firmware instead of the regular U. use patched odin 3.13.1b to flash it.( and flash all 4 files not just the AP.md5....)
also I belive that it might be region locked. usualy to lift that a 5 min call should have been made on US soil with proper carrier sim. if he never used it on us soil then that might have been the issue.

A N960U1 rom might work. use the CCT csc for it to be completely carrier less. thats the "Unknown" variant as opposed to XAA which is USA unlocked.
use this to download the file faster than the freemium download speed on sammobile

XAA and CCT have the same files, so does all other firmware under the XAA multi csc

they have the same files but depending on the csc it will load different configs for each. using CCT is the unknown variant so it should ask the sim card what region its in and hopefully sim unlock it.

the firmware file you dl is all the same regardless.
now on the device if you can manualy set the proper CSC code then yes that should work as you mentioned. but if nothing is modified, then system will just pick the appropriate or last csc that was set in root/efs/imei/mps code.dat
there is an other thread in the forums that has a procedure to force csc code for non rooted devices. it involves adb and flashing combo firmware if I'm not mistaken.

that very well may be the case. but at least before calling it quits might as well explore all available avenues.

Removing carrier branding from S20 FE (UK)

I have an S20 FE from Three UK. There is branding when you turn the phone on and off (their logo), so I downloaded and installed the UK BTU firmware however during set up it still installs the carrier extra software (Three app, Three branding etc despite me not having a Three SIM in during the process, I have an EE SIM instead) - there is no option not to install this software, it seems to be compulsory? I did think that putting on unbranded BTU firmware would solve this problem, but maybe not? Anyone got any pointers? Thank you. If I go into the phone settings and check the software version it still says H3G,H3G,etc instead of BTU?

Trying to debrand S20 FE 5G (SM-G781B)

I have an unlocked S20 FE 5G purchased from Three UK, and i'm trying to debrand it by replacing its factory android from three with the H3G csc code with an unlocked firmware with the BTU csc code, however when i try to flash with odin it stays the same (three uk bootlogo, three uk bloatware, H3G csc code). How can i properly debrand the phone and also change its CSC to BTU?
Hi how did you resolve this, please
Thanks

For this particular samsung s10 5g G977U model, there is no frimware available anywhere to chnage CSC. Do you know where can i find firmware or any other way to avoid bloatware?

If you're on att you can change it to xaa csc with Sam fw toolkit. I know because I've done it. Look up on Google SamFW toolkit and it will tell you how to change csc without switching firmware and xaa csc will unbloat it.

Question change the firmware

hello, i got the s23 from a different country (china) and I live in Tunisia. Can I change the firmware to my countrys one without any problems ? could this affect the device functions in any way ?
yes, you can change the firmware of your phone. First need identify the variant model of your phone to find the correct firmware to flash.

thank you, my model is SM-S9110 can i use the SM-S911B FIRMWARE or just another country with my same model SM-S9110 (in my case looks like only Taiwan or Hong Kong) ?
I have 911b
I want to change the firmware to 9110
Is it possible?
This is confusing to say the least:
Firmware variant change
Hello I have s23 s911b/ds I would install china firmware of variant s9110 Is it possible?
forum.xda-developers.com
From the looks of it the 911b has the same hardware as 9110.
I'm also curious if this would work - would love to put the 911b firmware on a 9110.
Via Odin you can't change a Chinese SM-S9110 to a US phone. You can change it to a Hong Kong or Taiwan phone. Hong Kong has Google Play preinstalled. Careful if you do try flashing the USA XAA variant to a Chinese phone, the phone will get stuck in a soft brick. None of the recovery methods online worked (emergency recovery etc.), I had to unlock the bootloader from the download menu, then it would boot again. I relocked it but the damage is done. Goodbye Samsung apps that rely on Knox security, they will never come back. Note I was able to flash Hong Kong firmware with the bootloader locked, which would have been ideal had I known that ahead of time.
i bought my SM-S9110 in mainland china today (from JD). surprisingly i could activate google services straight from the menu.
i couldn't find google play store in the phone so i installed it from apk. when running the install it said "update" rather than "install". so i guess play store was also already there somehow.
what i am confused about is eSIM. it seems not to have it. can't find it in the seetings and also on the box there where only stickers with the IMEIs for the physical SIM-slots.
would a SM-S9110 bought in HongKong have a eSIM functionality?
The SM-S9110 is the same hardware across China, Hong Kong, Taiwan. I followed the guide for activating the eSIM on US models (which only have 1 SIM card slot) and this phone doesn't have it. BTW I bought mine from JD.com as well, ordering in Chinese and using Google Translate JD apparently also sells the US model which has an eSIM, if that's what you want. But you can't root a US phone if that's what you are looking to do. I rooted mine just because I already tripped Knox, it isn't that difficult, and everything works except Samsung Pass and Wallet which I find pretty useless next to Google Pay, which also works rooted with the right Magisk modules.
I also recently just bought the SM-S9110 from JD, currently live in China. So just to make sure, I can only flash the HK version of the firmware if I want to get rid of the chinese stuff? Will that affect the warranty on my phone?
I have a SM-S911B/DS , can i flash it with SM-S911W ?

If you unlock bootloader then Samsung Pay can't be used on all firmware.
For Shealth ect is a patched app available or you can install KnoxPatch with LSPosed. Search on XDA.

before i had two S10e (one from Mainland SM-G9708, and one from Hongkong SM-G9700). i could both flash with the other ones firmware, and back. no problem. i guess would be the same with SM-S9110.
